Many times we manually add flux from the top side for good fill.

You're thinking correctly in trying to improve your process. Can you change to a more active flux? Look at the copper that connects to the center pin. You may need to relay-out the board to add a wagon wheel style thermal relief in that area.

I am a user of an Ersa Versaflow 3/45. I was wondering if anyone could share some process pointers. I have a 0.125" multilayer PCB that I am having problems consistently achieving 75 percent hole fill on a mini-coax connector. The coax connector ha

I believe that NORDSON now recommends AIM NC277. Nordson bought out ACE-protech.

Hi All, What are you running for selective solder flux? I'd like any opinion on water soluble and/or no-clean fluxes you are using. In our Kiss 104 machine we use HYDRO-X20 water soluble flux, per the original install suggestion, but I'd like to k

BLT 31-41 "No Clean Selective Flux For Aerospace" On a Versaflow 3/45 Atomises well, good hole penetration, good wetting, cleans off well in the solvent cleaner. Use for SN100C, SA0307, and 60/40.

Thank you ProcEng1 Nordson sent me a flux suggestion list: No Clean: 1. Kester Select 10 2. ALPHA EF-2210 3. AIM FX-16 Water Sol: KESTER 2331-ZX Nozzle Tinning: SUPERIOR #75

I personally prefer a NC process if I have to chose. AIM flux was good NC377 I think(they keep changing names), NF 372 from and many more. You can make them all work...the KISS 104 ...

What is your solder pot temperature? We found that on a 0.093" multilayer board increasing the temp of the lead free solder from 300C to 315C helped with the barrel fill.

In those cases where we have a 3.2mm thick, 16-layer board with several GND layers, do we still need ground connection to each and every layer (with thermal relief) or, skip part of the ground patterns? Will it help soldeing rising. I can't reach mor
